Lege Artis Medicinae - 2004;14(10)

[The author deals with the current situation and new trends of vaccinology by focusing on the interests of practitioners. The main topics are the changes of antigens (such as pertussis, measles, or poliomyelitis) to provide better efficacy and milder reactogenity or less adverse events. Purifying the vaccines, like thiomersal and human proteins free vaccines is another proven method to achieve better safety. New antigens e.g. Rota, Lyme, meningococcus B are in the pipeline of vaccinology. The aim of producing a combined vaccine is to achieve immunity against more diseases with less inconvenience for the patient, while achieving higher vaccine coverage (DPT-Hib-HBV-IPV). The epidemiological and clinical experiences will influence the current vaccine schedule such as revaccinations of MMR, and remove the need for revaccinations of BCG and hepaB. The special target groups of immunizations are the elderly and patients with chronic disease. Groups of specialists are working on the vaccine recommendation guidelines for certain risk groups. At the same time, with the successful eradication of polio in Europe the practitioners now have to face the antivaccination movement, as well. The main tools to convince people about the benefit of vaccinations are health education and information.]

[LONG-TERM RESULTS OF ENDOSCOPIC SPHINCTEROTOMY - EFFECTS OF THE TRANSECTION OF BILE PAPILLA]

DÖBRÖNTE Zoltán

[The abolishment of the choledochoduodenal pressure gradient due to endoscopic sphincterotomy results in the enhancement of the enterohepatic circulation of the bile salts, in the reduction of the cholesterol saturation index and in the modification of the gallbladder function: the reduced gallbladder storage time and the increased ejection fraction facilitates gallbladder emptying. On the contrary, bacterial colonisation of the bile ducts due to duodenobiliary reflux plays a causative role in the increased risk of pigment stone formation. However, when the biliary tree is well-drained, no clinically relevant chronic inflammation develops, furthermore there is no evidence for an increased cancer risk caused by the duodenobiliary reflux. Long-term complications may occur in about 12%, as the recurrence of common bile duct stones, post-EST papillary stenosis, and biliary symptoms caused by retained gallbladder stones. Risk factors for recurrence of bile duct stones are juxtapapillary duodenum diverticulae and persistently dilated bile ducts being the main reason for papillary restenosis and sphincterotomies are mainly performed because of papillary stenosis. In cases of retained gallbladder with stones patency of the cystic duct and contractility of the gallbladder are important predictive factors of late gallbladder complications as it was confirmed by our investigations. Accordingly, small gallbladder stones may pass spontaneously after EST. The indication of a cholecystectomy following EST should be considered individually, particularly in elderly patients. As 30-year-experience confirms, EST is a safe and effective treatment of choledocholithiasis and papillary stenosis even in the long term, and also in young patients. Regular follow-up of patients with high risk for recurrent biliary symptoms is recommended to detect late complications and treat them endoscopically in time.]

[THE SIGNIFICANCE OF THE CARE OF CHILDREN WITH CLEFT LIP AND PALATE IN THE GENERAL PRACTICE]

HIRSCHBERG Jenő

[The cleft lip and palate (i.e. facial cleft) is a frequent and distorting abnormality. The basics of the successful management are the early introduction of therapy and a well-trained team with all relevant specialists included (surgeon, otolaryngologist, orthodontist, speech therapist) as well as good collaboration with the parents and general practitioners being also an important factor. The author with his co-workers has performed more than 6000 surgeries in about 3500 children with facial cleft in the last 45 years and has treated 60-70 patients annuallly with velopharyngeal insufficiency without cleft. According to his experience and international data he summarizes the etiology, pathomechanism of facial clefts and discusses its symptoms, functional consequences and the surgical and conservative solutions are suggested. The recent Hungarian prevalence is 1:500. Specific prevention does not exist, the 5-6% recurrent cleft risk may be decreased to half by administration of folic acid. The generally accepted timing of the lip plasty is the 3-month age. The palatoplasty may be performed in one or two stages, but closure of the velum should be made before the development of speech by all means. The logopedic treatment (speech therapy) should be started, if the speech disorder is already obvious and the child is able to cooperate with the speech therapist. If conservative therapy is unsuccessful, (velo)pharyngoplasty is proposed at the age of 5. The orthodontic treatment should begin in mixed dentition, major nose correction and oral surgery are allowed only after puberty. Just because of a cleft the infant does not aspirate, the brestfeeding is beneficial and could be performed in most cases. Regular hearing control is recommended because of frequent ear and hearing problems. It is suggested to provide the parents with written instruction about outcome, prognosis and timetable of management, which could be helpful also for the general practitioners.]

[COST-EFFECTIVENESS OF PIMECROLIMUS CREAM - A NEW TREATMENT FOR ATOPIC DERMATITIS IN HUNGARY]

KÓSA József, HUNYADI János, SZALAI Zsuzsanna, KÖRMENDY Miklós, KALÓ Zoltán

[OBJECTIVE - To assess the costs, consequences and cost-effectiveness of pimecrolimus cream 1% in the treatment of children with atopic dermatitis in Hungary. METHODS - A Markov-model for atopic dermatitis developed by the Erasmus University (Rotterdam, the Netherlands) was adopted to the Hungarian health care setting. The model is based on a double-blind, multicenter, randomized, parallelgroup study. Patients were randomised (2:1) to receive pimecrolimus treatment (i.e. emollients, pimecrolimus, medium potency topical corticosteroids) or standard of care (emollients, vehicle, medium potency topical corticosteroids). The study was conducted in children and adolescents (2 to 18 years of age). Hungarian cost vectors were calculated by linking severity of disease as defined by Investigator’s Global Assessment (IGA) to average resource use. Resource use was multiplied by drug costs and unit costs as published in official databases. RESULTS - Pimecrolimus treatment has an incremental cost of HUF 143 897 over standard care. This additional cost of care resulted in an incremental 0.05 QALY gain over the 6 months period. The incremental cost effectiveness ratio was 2 863 913 HUF/QALY for the pimecrolimus therapy. CONCLUSION - Pimecrolimus is more costeffective than many other health care interventions currently reimbursed by the Hungarian National Health Fund.]

Electrophysiological investigation for autonomic dysfunction in patients with myasthenia gravis: A prospective study

NALBANTOGLU Mecbure, AKALIN Ali Mehmet, GUNDUZ Aysegul, KIZILTAN Meral

Myasthenia gravis (MG) is an autoimmune disorder of neuromuscular transmission. Autonomic dysfunction is not a commonly known association with MG. We conducted this study to evaluate autonomic functions in MG & subgroups and to investigate the effects of acetylcholinesterase inhibitors. This study comprised 30 autoimmune MG patients and 30 healthy volunteers. Autonomic tests including sympathetic skin response (SSR) and R-R interval variation analysis (RRIV) was carried out. The tests were performed two times for patients who were under acetylcholinesterase inhibitors during the current assessment. The RRIV rise during hyperventilation was better (p=0.006) and Valsalva ratio (p=0.039) was lower in control group. The SSR amplitudes were lower thereafter drug intake (p=0.030). As much as time went by after drug administration prolonged SSR latencies were obtained (p=0.043).Valsalva ratio was lower in the AchR antibody negative group (p=0.033). The findings showed that both ocular/generalized MG patients have a subclinical parasympathetic abnormality prominent in the AchR antibody negative group and pyridostigmine has a peripheral sympathetic cholinergic noncumulative effect.

[Second game, 37th move and Fourth game 78th move]

VOKÓ Zoltán

[What has Go to do with making clinical decisions? One of the greatest intellectual challenges of bedside medicine is making decisions under uncertainty. Besides the psychological traps of traditionally intuitive and heuristic medical decision making, lack of information, scarce resources and characteristics of doctor-patient relationship contribute equally to this uncertainty. Formal, mathematical model based analysis of decisions used widely in developing clinical guidelines and in health technology assessment provides a good tool in theoretical terms to avoid pitfalls of intuitive decision making. Nevertheless it can be hardly used in individual situations and most physicians dislike it as well. This method, however, has its own limitations, especially while tailoring individual decisions, under inclusion of potential lack of input data used for calculations, or its large imprecision, and the low capability of the current mathematical models to represent the full complexity and variability of processes in complex systems. Nevertheless, clinical decision support systems can be helpful in the individual decision making of physicians if they are well integrated in the health information systems, and do not break down the physicians’ autonomy of making decisions. Classical decision support systems are knowledge based and rely on system of rules and problem specific algorithms. They are utilized widely from health administration to image processing. The current information revolution created the so-called artificial intelligence by machine learning methods, i.e. machines can learn indeed. This new generation of artificial intelligence is not based on particular system of rules but on neuronal networks teaching themselves by huge databases and general learning algorithms. This type of artificial intelligence outperforms humans already in certain fields like chess, Go, or aerial combat. Its development is full of challenges and threats, while it presents a technological breakthrough, which cannot be stopped and will transform our world. Its development and application has already started also in the healthcare. Health professionals must participate in this development to steer it into the right direction. Lee Sedol, 18-times Go world champion retired three years after his historical defeat from AlphaGo artificial intelligence, be­cause “Even if I become the No. 1, there is an entity that cannot be defeated”. It is our great luck that we do not need to compete or defeat it, we must ensure instead that it would be safe and trustworthy, and in collaboration with humans this entity would make healthcare more effective and efficient. ]

The effect of sniffing Turkish coffee on olfactory disorders in COVID-19 patients: An experimental clinical study

BULBULOGLU Semra, ALTUN Yasar

The current study aimed to examine the effect of sniffing Turkish coffee on the sense of smell in COVID-19 patients. This study utilized the experiment-control method. Data were collected using a patient and disease information form and the Connecticut Chemosensory Clinical Research Center (CCCRC) Test. An experimental group of patients sniffed Turkish coffee, and the coffee’s effect on the patients’ sense of smell was examined. All data were analyzed using SPSS version 25 (IBM). Of the patients in the experimental group, 25% had moderate hyposmia, 58.3% had severe hyposmia, and 16.7% had anosmia prior to sniffing Turkish coffee. After sniffing the Turkish coffee, 13.3% of these patients regained their ability to smell normally, while 18.3% had mild hyposmia, 45% had moderate hyposmia, 6.7% had severe hyposmia, and 16.7% had anosmia. There was no difference in the control group between first and second measurement. COVID-19 patients who sniffed Turkish coffee intermittently regained some of their sense of smell for one hour. Turkish coffee is cheap, fragrant, widely available, and easy to access. Therefore, results of this study suggest that it may be recommended for treating olfactory disorder in COVID-19 patients.

The effects of 30 Hz, 50 Hz AND 100 Hz continuous theta burst stimulation via transcranial magnetic stimulation on the electrophysiological parameters in healthy individuals

OZDEMIR Zeynep, ACAR Erkan, SOYSAL Aysun

Transcranial magnetic stimulation is a non-invasive procedure that uses robust magnetic fields to create an electrical current in the cerebral cortex. Dual stimulation consists of administering subthre­shold conditioning stimulation (CS), then suprathreshold test stimulation (TS). When the interstimulus interval (ISI) is 1-6 msec, the motor evoked potential (MEP) decreases in amplitude; this decrease is termed “short interval intracortical inhibition” (SICI); when the ISI is 7-30 msec, an increase in MEP amplitude occurs, termed “short interval intracortical facilitation” (SICF). Continuous theta burst stimulation (cTBS), often applied at a frequency of 50 Hz, has been shown to decrease cortical excitability. The primary objective is to determine which duration of cTBS achieves better inhibition or excitation. The secondary objective is to compare 50 Hz cTBS to 30 Hz and 100 Hz cTBS. The resting motor threshold (rMT), MEP, SICI, and SICF were studied in 30 healthy volunteers. CS and TS were administered at 80%-120% and 70%-140% of rMT at 2 and 3-millisecond (msec) intervals for SICI, and 10- and 12-msec intervals for SICF. Ten individuals in each group received 30, 50, or 100 Hz, followed by administration of rMT, MT-MEP, SICI, SICF immediately and at 30 minutes. Greater inhibition was achieved with 3 msec than 2 msec in SICI, whereas better facilitation occurred at 12 msec than 10 msec in SICF. At 30 Hz, cTBS augmented inhibition and suppressed facilitation, while 50 Hz yielded less inhibition and greater inter-individual variability. At 100 Hz, cTBS provided slight facilitation in MEP amplitudes with less interindividual variability. SICI and SICF did not differ significantly between 50 Hz and 100 Hz cTBS. Our results suggest that performing SICI and SICF for 3 and 12 msec, respectively, and CS and TS at 80%-120% of rMT, demonstrate safer inhibition and facilitation. Recently, TBS has been used in the treatment of various neurological diseases, and we recommend preferentially 30 Hz over 50 Hz cTBS for better inhibition with greater safety and less inter-individual variability.

[Tobacco use habits and cessation support tasks in Hungary. PART 1.]

CSELKÓ Zsuzsa, FÉNYES Márta, CSÁNYI Péter, BOGOS Krisztina, KISS Judit, DEMJÉN Tibor

[Today, non-communicable diseases and their underlying main risk factors, namely tobacco use, physical inactivity, excessive alcohol intake and unhealthy diet are responsible for almost 70% of the mortality worldwide. The Global Ac­tion Plan issued for the preven­tion and control of non-communicable diseases aims among others to reduce smoking rates by 30% as compared to the 2010 prevalence. The aim of the World Health Or­ga­ni­zation (WHO) in ac­cor­dance with the United Nations Sus­tai­nable Development Goals (UN SDG 2030) proposes to achieve a 23% target rate in Hun­gary by 2025. Based on the current smo­king prevalance (29%) and preliminary estimates this goal will not be accomplished. It is highly concerning that while the con­sumption of traditional tobacco products does not decrease at the expected rate in Hungary, novel nicotine and tobacco products are spreading worldwide and in Hungary as well. Thus in order to curb tobacco use, more ro­bust actions are needed in Hungary. More emphasis should be laid on the provisions of the WHO Fra­mework Con­vention on Tobacco Control (FCTC). This document re­com­mends to in­crease the tax rate of to­bacco products, declares to halt the spread of novel nicotine and tobacco products, and urges health care requirements to support smokers in quit­ting. The present summary describes the smoking cessation support related tasks of the health care in­dust­ry, taking into ac­count current national smoking habits. ]
